The test found that there is a problem with https tls hand error after one year of use of K3s, and it is not good to regenerate the certificate. K3s can only be reinstalled through source code compilation and repair.
Environment: ubuntu 16.04
Docker 18.06.3
Install git (default should already be installed. If not, please execute the following command)
Sudo apt install-y git
Second, clone source code, and switch branches (I am using v1.0.1 version here)
Git clone https://github.com/rancher/k3s.git
Cd k3s
Git checkout-b v1.0.1
Modify the part of the certificate in the source code
Mainly three files, modified as shown in the figure
1. The first file
Vendor/github.com/rancher/dynamiclistener/cert/cert.go
Although the official revision has been made for 100 years, it does not seem to say the effect.
two。 The second file, vendor/github.com/rancher/dynamiclistener/factory/cert_utils.go
3. The third file, scripts/version.sh, because the file sa value is checked, comment 4-7 lines
IV. Compile (make sure you can connect to the Internet, as it is compiled in docker)
1. Install make
Apt install-y make
two。 Execute make command directly. It takes a long time to compile. Please wait patiently.
3. Complete all the files in dist/artifacts
V. Verification
Reinstall K3s (please refer to K3s installation for installation). If you are using an official offline package, there is a small bug that needs to tag image.
Docker tag k8s.gcr.io/pause:3.1 rancher/pause:3.1
Results of verification
At this point, you can feel at ease to use it for 100 years, and you don't have to upgrade every year. Of course, it is recommended to upgrade once a year, just like the official one. After all, there are many loopholes.
